Doxygenified some comments in IRBuilder.h.
Restrict sin/cos optimization to 64-bit only for now. 32-bit is a bit messy and less critical.
Forgot the test case before.
expressions + C++11 lambdas == cooooool!!!

C++11 lambdas that don't capture anything can be used as static callback functions!

Heavily modified this python module to be able to not require a dylib in order to traverse the heap allocations.

Re-implemented the ptr_refs, objc_refs, malloc_info and cstr_refs to use complex expressions that use lambdas to do all static callback function work.
